Gosh, I LOVE this house. It's one of my favorite things from Gen III.
I like all the puzzles, but it is kinda annoying when you have to use HMs. I think I managed to complete all the puzzles...Did they reward you with something by completing all?

Anyways, I hope they add something like this in X and Y.

Nope just the prizes after completing every Trick Puzzle. You do get an exclusive tent though for your Secret Base at the end.
